Problems solved by technology

[0003] In existing protocols, BWP can be activated or switched based on the indication information contained in the BWP indication field in DCI signaling; if the DCI signaling does not include the BWP indication field, then only the currently effective BWP can be used for data transmission , the dynamic configuration of BWP cannot be realized
Among them, the currently effective BWP is usually the default BWP. The default BWP is for UE energy saving considerations, and the bandwidth is usually small, which cannot be applied to the needs of low-latency and high-reliability communication (URLLC, Ultra Reliable&Low LatencyCommunication) services.

Embodiment 1

[0043] see figure 2 , which shows a resource configuration method provided by an embodiment of the present invention, the method is applied to a UE, and the method includes:

[0044] S201: Receive control information;

[0045] S202: Transmit the data scheduled by the control information; wherein, the bandwidth part BWP configuration corresponding to the data scheduled by the control information is determined by the mapping relationship between the parameters of the control information and the BWP configuration corresponding to the data scheduled by the control information.

[0046] pass figure 2 From the technical solution shown, it can be seen that when the network device sends the control information, the parameters of the control information implicitly represent the BWP configuration of the information, so that the UE uses the BWP configuration used by the network device when receiving the control information sent by the network device. The parameter of the control info...

[0056] For the DCI format Format, it may specifically include: the user-specific DCI format that does not include the BWP indication field. It should be noted that, among the currently existing DCI Formats, neither the compressed DCI Format nor the fallback DCI Format includes the BWP indication field.

[0057] Based on this, the bandwidth part BWP configuration corresponding to the data scheduled by the control information is determined by the mapping relationship between the parameters of the control information and the BWP configuration corresponding to the data scheduled by the control information, including:

[0058] Corresponding to the fact that the DCI Format is a compressed DCI Format, determine that the BWP configuration corresponding to the data scheduled by the compressed DCI Format is the first BWP configuration information; and / or

[0059] Corresponding to the fact that the DCI Format is a fallback DCI Format, determine that the BWP configuration corresponding to...

example 2

[0065] At least one indication field in the DCI may include a time domain resource indication field of the DCI; and / or a frequency domain resource indication field of the DCI. The time-domain resource indication field of DCI may include a transmission time interval (TTI, Transmission TimeInterval) length Length and a physical downlink shared channel (PDSCH, Physical Downlink SharedCHannel) type type; and the frequency-domain resource indication field of DCI may exemplarily include frequency Domain resource indication type and frequency domain scheduling bandwidth.

[0066] For the time-domain resource indication field of DCI, optionally, the bandwidth part BWP configuration corresponding to the data scheduled by the control information is configured through the mapping relationship between the parameters of the control information and the BWP configuration corresponding to the data scheduled by the control information OK, including:

[0067] Determine whether the TTI Length s...

Abstract

Embodiments of the present invention provide a resource configuration method, device, and computer storage medium; the method may include: receiving control information; transmitting data scheduled by the control information; wherein, the bandwidth part corresponding to the data scheduled by the control information The BWP configuration is determined by the mapping relationship between the parameters of the control information and the BWP configuration corresponding to the data scheduled by the control information. There is no need to explicitly indicate through the DCI indication field in the DCI, which not only reduces the length of the DCI Format, but also enables dynamic configuration of the BWP.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of wireless communication, and in particular, to a resource configuration method, device, and computer storage medium. Background technique [0002] In the fifth generation (5G, 5th Generation) new wireless (NR, New Radio) system, the system bandwidth supported by NR is greatly improved, and the transmission bandwidth of the terminal may only occupy a part of the system bandwidth. Based on the above situation, in order to improve scheduling efficiency, NR introduces the concept of Band Width Part (BWP, Band Width Part) to implement frequency domain resource allocation in a range smaller than the system bandwidth. In NR, a carrier can contain up to four bandwidth parts (Bandwidth Part, BWP), and each BWP mainly includes three parameters: basic parameter set Numerology, center frequency point, and bandwidth. [0003] In existing protocols, BWP can be activated or switched based on th...
